Residents across Gauteng are being urged to take precautions as the province experiences its first official heatwave of the 2026/27 summer season, with temperatures forecast to climb as high as 35°C in Pretoria.
The heatwave began on Friday and is expected to intensify on Sunday before continuing through Monday. The prolonged spell of hot weather is likely to affect daily routines, particularly for people who work outdoors, commuters and those planning sporting or recreational activities.
According to Gauteng Weather, Pretoria is forecast to record the highest temperature among the three cities highlighted in the forecast, reaching 35°C. Johannesburg could experience maximum temperatures of 33°C, while Vereeniging is expected to reach 32°C.
The hot conditions are not limited to Gauteng. Parts of the Mpumalanga Highveld, the southern Mpumalanga Lowveld and the south-western bushveld of Limpopo are also expected to experience persistently high temperatures.
Residents have been encouraged to monitor weather updates and make practical changes to their routines while the heatwave continues.
Extreme heat raises health concerns
Prolonged exposure to high temperatures can place additional strain on the body, increasing the risk of dehydration, heat exhaustion and potentially life-threatening heatstroke.
Children, older people and individuals with underlying health conditions are among those who need to take particular care during periods of extreme heat. People spending extended periods outdoors should also be mindful of their exposure and take regular breaks in cooler surroundings.
Staying hydrated is one of the key precautions recommended during hot weather. Residents should drink water regularly throughout the day rather than waiting until they feel thirsty.
Alcohol and excessive coffee consumption should be avoided or limited, as these can complicate hydration for some people, particularly when combined with prolonged exposure to heat. Light meals are also recommended, while very spicy foods may be less comfortable for some people in hot conditions.
Outdoor activities should, where possible, be scheduled away from the hottest parts of the day. Those who need to be outside are encouraged to seek shade or shelter whenever possible.
Sunscreen, sunglasses and hats can provide additional protection from direct sunlight. Wearing loose-fitting, light-coloured clothing may also help people remain more comfortable during periods of intense heat.
Households and pet owners urged to prepare
The heatwave may affect people both at home and in the workplace. Residents are encouraged to keep indoor spaces adequately ventilated and consider measures to stay cool, including taking cool showers when necessary.
Employers and people working outdoors should pay attention to the conditions and consider appropriate breaks and access to drinking water during particularly hot periods.
Pet owners have also been reminded that animals need protection from extreme temperatures. Pets should have access to shaded areas and fresh drinking water throughout the day. Owners should avoid leaving animals in hot, enclosed spaces and should remain alert to signs that their pets may be struggling with the heat.
The forecast heatwave could add pressure to commuters and people participating in outdoor exercise or organised sporting events. Adjusting activity schedules and avoiding unnecessary exposure during peak heat can help reduce the risks associated with prolonged hot weather.
Although temperatures are expected to begin easing after Monday, residents should not assume that conditions will immediately return to normal. Local temperatures can vary, and updated forecasts remain important for planning activities safely.
Gauteng residents are therefore advised to follow the latest weather information, remain hydrated and take extra care of vulnerable people and animals until the extreme conditions subside.
The forecast indicates that the heatwave will persist through Monday, with temperatures expected to ease afterwards.
